MACHINE FOR BOLTING, AND CLEANING CLOVER-SEED.

Specification forming part; of Lettersliatent No, 26,409,, dated:December 13,, 18,59; Reissued November 12, 1867, No. 2,79;

To all whom it may concern:

Be it known that I, JoHN C. BIRDSELL, of West Henrietta, Monroe county,State of New York, have invented certain new and useful Improvements inBolting and CleaningCloVer-Seed; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings and to the letters of referencemarked thereon.

Figure 1, is a side elevation of the machine exhibiting only the boltingand conveying process. Fig. 2, shows one end of the same. Fig. 3, is theopposite end of Fig. 1. Fig. 4, exhibits the bolts in two positions witha part of the frame of the machine detached.

The nature of my invention consists in giving to the twobolts, when themachine is in operation, an oblique, alternating motion, so that theywill alternately raise and fall keeping at the same time always parallelto each other, for the purpose of more effectually separating the cupsor bowls'containing the clover seed, from the straw, by giving it adropping motion, while at the same time it is propelled to the rear ofthe machine. Also in providing an endless conveyer so arranged that itwill convey the tailings which have not been effectually hulled back tobe again submitted to the process of hulling, for the purpose of morethoroughly freeing it of its hulls, described represented and specifiedas follows.

As the present claims will only refer to the bolting and conveyingoperation therefore it is not necessary to exhibit the entire machine inthe drawings, but only the several parts herein referred thereto.

A, A, represents the two bolts which are hung parallel to each other andare operated by means of connecting rods B, B which are attached to acrank shaft C the rod B being attached to crank D placed in the centerof the shaft C and connecting about midway with the lower bolt A givesmotion to the lower bolt. The rods B connecting with the cranks E E oneach side of the machine but on the opposite side of the shaft C tocrank D, thus giving a double crank motion to the connecting rods B andB, these rods B pass along each side of the machine and are attached tothe sides of the upper bolt A.

F F are inclined guides which pass through the cross ties a; a on eachside of the bolts and upon which the bolts rest and are guided in theirmotions.

G are arms, one of which is shown in the drawing which are pivotedrespectively to the frame of the machine and to the upper bolt. A.

H H are rods which connect the lower bolt with the frame of the machineand upon which the end of the lower bolt rests. this arrangement ofcranks, connecting rods, and guides, the bolts, as they are pushedforward, will rise and carry the straw with them, and as they recede anddrop, they slide from under the straw leaving it very nearly. at thepoint to which it was carried. Thus the straw after it has passedthrough the threshing cylinder is gradually moved backward and finallyejected at the rear of the machine, this dropping motion at the sametime serving to effectively separate the clover cups or bowls whichcontain the seed from the straw.

The clover cups or bowls which contain the seed and also the tailingsafter they have passed through the several operations of bolting asabove described and hulling and fanning, it is necessary to pass thosewhich have not been effectually hulled again through the operation ofhulling and fanning in order to render their separation perfeet. Inorder to accomplish this operation with greater facility I arrange uponthe side of my machine a trough I provided with conveyers J attached toendless bands K this trough I receives the tailings &c from the sievesthrough a spout into the conveyer I from whence they are taken by theconveyer J and carried up to any convenient place of deposit to bere-hulled and refanned.

The conveyers are operated by a pulley N and band P which is attached tothe threshing cylinder shaft or it may be carried over any otherconvenient pulley to give it motion. This arrangement dispenses with thetime and labor of handling the clover tailings and carrying it from oneend of the machlne to the other.

I do not claim giving to the bolts a vibratory motion as is common tosieves of clover hullers now in constant use, nor do I claim hangingthem on cranks as patented by Mr. Pierpoint in wheat machines but What Iclaim as my invention, is

1. Operating the bolts A, A, so as to impart to them an obliquealternately rising and falling motion by means of double cranks D, Eguide rods F F arms G H and connecting rods B B or their equivalents, in5 the manner and for the purposes set forthit being understood that Iclaim the above only when applied to bolting clover seed.

2. I claim arranging a trough I provided with endless eonveyers J as setforth for the purpose of returning the unhulled seed or 10 tailmgs to beagain submitted to the operation of hulling as herein above described.JOHN C. BIRDSELL. Witnesses:
